+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Service Description: Service for managing
+ * [DataStore][google.cloud.discoveryengine.v1alpha.DataStore] configuration.
+ *
+ * 
This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (DataStoreServiceClient dataStoreServiceClient = DataStoreServiceClient.create()) {
+ *   DataStoreName name =
+ *       DataStoreName.ofProjectLocationDataStoreName("[PROJECT]", "[LOCATION]", "[DATA_STORE]");
+ *   DataStore response = dataStoreServiceClient.getDataStore(name);
+ * }
+ * }

+ *
+ * 
Note: close() needs to be called on the DataStoreServiceClient object to clean up resources
+ * such as threads. In the example above, try-with-resources is used, which automatically calls
+ * close().
+ *
+ * 
The surface of this class includes several types of Java methods for each of the API's
+ * methods:
+ *
+ * 
    
+ *   
  1. A "flattened" method. With this type of method, the fields of the request type have been
+ *       converted into function parameters. It may be the case that not all fields are available as
+ *       parameters, and not every API method will have a flattened method entry point.
+ *   
  2. A "request object" method. This type of method only takes one parameter, a request object,
+ *       which must be constructed before the call. Not every API method will have a request object
+ *       method.
+ *   
  3. A "callable" method. This type of method takes no parameters and returns an immutable API
+ *       callable object, which can be used to initiate calls to the service.
+ * 

+ *
+ * 
See the individual methods for example code.
+ *
+ * 
Many parameters require resource names to be formatted in a particular way. To assist with
+ * these names, this class includes a format method for each type of name, and additionally a parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
This class can be customized by passing in a custom instance of DataStoreServiceSettings to
+ * create(). For example:
+ *
+ * 
To customize credentials:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * DataStoreServiceSettings dataStoreServiceSettings =
+ *     DataStoreServiceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * DataStoreServiceClient dataStoreServiceClient =
+ *     DataStoreServiceClient.create(dataStoreServiceSettings);
+ * }

+ *
+ * 
To customize the endpoint:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * DataStoreServiceSettings dataStoreServiceSettings =
+ *     DataStoreServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * DataStoreServiceClient dataStoreServiceClient =
+ *     DataStoreServiceClient.create(dataStoreServiceSettings);
+ * }

+ *
+ * 
To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * DataStoreServiceSettings dataStoreServiceSettings =
+ *     DataStoreServiceSettings.newHttpJsonBuilder().build();
+ * DataStoreServiceClient dataStoreServiceClient =
+ *     DataStoreServiceClient.create(dataStoreServiceSettings);
+ * }

+ *
+ *

+/**
+ * Settings class to configure an instance of {@link DataStoreServiceClient}.
+ *
+ * 
The default instance has everything set to sensible defaults:
+ *
+ * 
    
+ *   
  • The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   
  • Credentials are acquired automatically through Application Default Credentials.
+ *   
  • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 

+ *
+ * 
The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
For example, to set the total timeout of getDataStore to 30 seconds:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * DataStoreServiceSettings.Builder dataStoreServiceSettingsBuilder =
+ *     DataStoreServiceSettings.newBuilder();
+ * dataStoreServiceSettingsBuilder
+ *     .getDataStoreSettings()
+ *     .setRetrySettings(
+ *         dataStoreServiceSettingsBuilder
+ *             .getDataStoreSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setTotalTimeout(Duration.ofSeconds(30))
+ *             .build());
+ * DataStoreServiceSettings dataStoreServiceSettings = dataStoreServiceSettingsBuilder.build();

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Service Description: Service for managing [Engine][google.cloud.discoveryengine.v1alpha.Engine]
+ * configuration.
+ *
+ * 
This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (EngineServiceClient engineServiceClient = EngineServiceClient.create()) {
+ *   Engine engine = Engine.newBuilder().build();
+ *   FieldMask updateMask = FieldMask.newBuilder().build();
+ *   Engine response = engineServiceClient.updateEngine(engine, updateMask);
+ * }
+ * }

+ *
+ * 
Note: close() needs to be called on the EngineServiceClient object to clean up resources such
+ * as threads. In the example above, try-with-resources is used, which automatically calls close().
+ *
+ * 
The surface of this class includes several types of Java methods for each of the API's
+ * methods:
+ *
+ * 
    
+ *   
  1. A "flattened" method. With this type of method, the fields of the request type have been
+ *       converted into function parameters. It may be the case that not all fields are available as
+ *       parameters, and not every API method will have a flattened method entry point.
+ *   
  2. A "request object" method. This type of method only takes one parameter, a request object,
+ *       which must be constructed before the call. Not every API method will have a request object
+ *       method.
+ *   
  3. A "callable" method. This type of method takes no parameters and returns an immutable API
+ *       callable object, which can be used to initiate calls to the service.
+ * 

+ *
+ * 
See the individual methods for example code.
+ *
+ * 
Many parameters require resource names to be formatted in a particular way. To assist with
+ * these names, this class includes a format method for each type of name, and additionally a parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
This class can be customized by passing in a custom instance of EngineServiceSettings to
+ * create(). For example:
+ *
+ * 
To customize credentials:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EngineServiceSettings engineServiceSettings =
+ *     EngineServiceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * EngineServiceClient engineServiceClient = EngineServiceClient.create(engineServiceSettings);
+ * }

+ *
+ * 
To customize the endpoint:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EngineServiceSettings engineServiceSettings =
+ *     EngineServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * EngineServiceClient engineServiceClient = EngineServiceClient.create(engineServiceSettings);
+ * }

+ *
+ * 
To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EngineServiceSettings engineServiceSettings =
+ *     EngineServiceSettings.newHttpJsonBuilder().build();
+ * EngineServiceClient engineServiceClient = EngineServiceClient.create(engineServiceSettings);
+ * }

+ *
+ * 
Please refer to the GitHub repository's samples for more quickstart code snippets.

+/**
+ * Settings class to configure an instance of {@link EngineServiceClient}.
+ *
+ * 
The default instance has everything set to sensible defaults:
+ *
+ * 
    
+ *   
  • The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   
  • Credentials are acquired automatically through Application Default Credentials.
+ *   
  • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 

+ *
+ * 
The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
For example, to set the total timeout of updateEngine to 30 seconds:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EngineServiceSettings.Builder engineServiceSettingsBuilder = EngineServiceSettings.newBuilder();
+ * engineServiceSettingsBuilder
+ *     .updateEngineSettings()
+ *     .setRetrySettings(
+ *         engineServiceSettingsBuilder
+ *             .updateEngineSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setTotalTimeout(Duration.ofSeconds(30))
+ *             .build());
+ * EngineServiceSettings engineServiceSettings = engineServiceSettingsBuilder.build();
+ * }

+/**
+ * Settings class to configure an instance of {@link DataStoreServiceStub}.
+ *
+ * 
The default instance has everything set to sensible defaults:
+ *
+ * 
    
+ *   
  • The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   
  • Credentials are acquired automatically through Application Default Credentials.
+ *   
  • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 

+ *
+ * 
The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
For example, to set the total timeout of getDataStore to 30 seconds:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * DataStoreServiceStubSettings.Builder dataStoreServiceSettingsBuilder =
+ *     DataStoreServiceStubSettings.newBuilder();
+ * dataStoreServiceSettingsBuilder
+ *     .getDataStoreSettings()
+ *     .setRetrySettings(
+ *         dataStoreServiceSettingsBuilder
+ *             .getDataStoreSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setTotalTimeout(Duration.ofSeconds(30))
+ *             .build());
+ * DataStoreServiceStubSettings dataStoreServiceSettings = dataStoreServiceSettingsBuilder.build();

+/**
+ * Settings class to configure an instance of {@link EngineServiceStub}.
+ *
+ * 
The default instance has everything set to sensible defaults:
+ *
+ * 
    
+ *   
  • The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   
  • Credentials are acquired automatically through Application Default Credentials.
+ *   
  • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 

+ *
+ * 
The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
For example, to set the total timeout of updateEngine to 30 seconds:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EngineServiceStubSettings.Builder engineServiceSettingsBuilder =
+ *     EngineServiceStubSettings.newBuilder();
+ * engineServiceSettingsBuilder
+ *     .updateEngineSettings()
+ *     .setRetrySettings(
+ *         engineServiceSettingsBuilder
+ *             .updateEngineSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setTotalTimeout(Duration.ofSeconds(30))
+ *             .build());
+ * EngineServiceStubSettings engineServiceSettings = engineServiceSettingsBuilder.build();
